Genetic variability for Russian wheat aphid, Diuraphis noxia resistance in South African wheat genotypes
(University of the Free State, 2006-07)
Near-isogenic genotypes 1684/Tugela and 2199/Tugela containing D. noxia resistance ex SA1684 [PI 137739 (Dn1)] and SA 2199 [PI 262660 (Dn2)] were studied in terms of antibiosis, antixenosis and tolerance, population ...
Molecular markers for and quality assessment of near isogenic palmiet and SST66 wheat lines for Pmeudocercosporella herpotrichoides (eyespot) resistance
(University of the Free State, 2000-11)
English: 1. The aim of this study was to determine whether the presence of the Pch 1 gene, has an effect on breadmaking quality and yield in two genetic backgrounds, to find a molecular marker linked to the gene, using ...
The improvement of leaf rust resistance in selected bread wheat lines
(University of the Free State, 2002-11)
English: The objective of this study was not only to improve leaf rust (caused by Puccinia triticina) resistance in selected wheats (Triticum aestivum L.), but to focus on durability as well as agronomic acceptability ...
Isolation and characterization of a possible polygalacturonase: inhibiting protein from wheat
(University of the Free State, 2001)
English: The presence and possible role of polygalacturonase-inhibiting protein (PGIP) in wheat (Triticum aestivum) as part of the plant's defense reaction following leaf rust (Puccinia triticina) infection were ...
Proteomic analysis and physiological response of wheat treated with a triglyceride purified from Lupinus albus L. seed
(University of the Free State, 2013)
English: The agricultural use of bio-stimulants to increase crop yield is increasing as a result of the ever growing human population. Since bio-stimulants do not have the negative environmental effects usually associated ...
